The combined effects of magnetic asymmetry, assembly and manufacturing tolerances on the plasma heat load to the ITER first wall
TL;DR: In this paper, a probabilistic combination of individual penalty coefficients is presented to give a global penalty coefficient, which ranges from 1.37 to 2.44, depending on the first wall row and plasma phase.

TL;DR: Experimental simulations of ITER-like transient events with relevant surface heat load parameters (energy density up to 1.1 MJ/m2 and the pulse duration of 0.25 ms) as well as particle loads (varied in wide range from 1023 to 1027 ion/m 2 s) were carried out with a quasistationary plasma accelerator QSPA Kh-50.

Velocity shear, turbulent saturation, and steep plasma gradients in the scrape-off layer of inner-wall limited tokamaks
TL;DR: In this article, the authors studied the narrow power decay-length of the scrape-off layer (SOL) of inner-wall limited (IWL) discharges in tokamaks using 3D, flux-driven, global two-fluid turbulence simulations.
